Bullseye on RPi needs addition to installation guidelines

[Swell1]

I've been using your wonderful script for 2 years or more. I have used two RPi Zero W with Buster on them and the wsprd.
This week I resumed using them after a long time and updated and upgraded both. In one case the udev rules problem came up. So I put Bullseye on that SD card and tried again.

Error messages :

1. Dev rules not being installed, install them with _DINSTALL_UDEV_RULES=ON
2. Building with usfbs zero-copy support disabled, use _DENABLE_ZEROCOPY=ON to enable
   3 At the end the message was "warning: manually specified variables were not used by the project: CMAKE_INSTALL_PREFIX

I deleted the rtl-sdr and rtlsdr-wsprd folders and rebooted. Then fumbled a bit. Then finally I added the two items above in the middle of your script line that starts with 'cmake -DCMAKE_ '
Thank God, everything worked perfectly.
Screenshots available for your reference if needed.

I hope this will help to make any necessary changes to instructions on GitHub, regarding use of Bullseye for rtlsdr_wsprd

Hi, thanks for your report. Not sure to understand your point n°2. This option _DENABLE_ZEROCOPY=ON seems to enable this zero-copy mode. But feel free to post an MR to fix the README.

Hello, thanks for your quick reply. I have been tied up in reinstalling my OS.
Not familiar with coding so I'm sending the screenshots for your reference.
I've named all the images appropriately, hope they can be made out.
I regret that I could not do better, Guenael, please let me know how else I can contribute

New user; caught my first 'spot' on 6M this weekend and have successfully got rtlsdr-wsprd running as both an installed set of packages and via Docker. Top stuff. Thank you so much.

Two questions:

1. Via 'rtlsdr_wsprd' or 'docker run', how might we pass argument for "PPM factor"?
2. Via 'rtlsdr_wsprd' or 'docker run', how might we specify an RTL-SDR dongle other than the default device 0?

Thanks again!

Found it!

Answer 1: we can pass an argument for PPM using -p like so:

user@pi:~ $ docker run -it --pull=missing --device=/dev/bus/usb ghcr.io/guenael/rtlsdr-wsprd:latest -f 2m -c AB#CD -l EF##gh -g 30 -p -5

or

user@pi:~ $ rtlsdr-wsprd -f 2m -c AB#CD -l EF##gh -g 30 -p -5

Answer 2: on a RaspberryPi4 running RaspbianOS (bullseye), whichever device plugged into the lower of the two USB3.0 ports gets assigned 'device 0' and gets used by rtlsdr-wsprd. Ensure that's the RTL-SDR dongle you want to use here, and dongles for other services in other ports.
